I don't know if that is how its implemented, but it makes sense.

In the interview, Larry Wagner said he needed 64 for the pieces, so I'm assuming he used them all and wasted the bits. In the 2600 sometimes the overhead of RAM optimization takes too long to be practical, or wastes more memory in the process (RAM or ROM).

One of the cool things about Video Chess is that you can set up unrealistic boards, for instance, 16 rooks vs. 16 knights.
